Paul,

I’ve added my responses to your questions below in blue that I believe answer all your questions. Please let
me know if you need anything else.
Thanks,

Jon,

I have just a couple of questions/comments about the chlorination on this project:

1) You mention that sodium hypochlorite will be used. I need to know that this type of sodium hypochlorite is ANSI/NSF
60 certified. The reason I ask is because typically sodium hypochlorite is about 12.5% concentration and what comes in
5.25% concentration is typically bleach, which is not allowed as a disinfectant.
The attached datasheet is for 5.25% sodium hypochlorite and is NSF 60 certified. It is available in 5 gallon
carboys (see website below)

Sodium Hypochlorite 5.25% – Alliance Chemical

2) Is the Blue-White Flexflow M14-4T peristaltic pump ANS/NSF 61 certified for drinking water use?
Yes. See attached Technical Data Sheet

3)There should be some method of secondary containment (like a tray, for example) in the event the primary container
leaks.
Keynote 9 on Drawing M1.0 identifies the sodium hypochlorite 5 gal carboy in a 6-gallon minimum spill containment bin.
Detail 2 on Drawing M-02 calls out the overflow spill container and refers back to the Mechanical plan for the size.

4) Sodium hypochlorite above 5% strength requires some method of eyewash as described below in red. This should be
described in the project how this will be done but it really can be as simple as an eye wash bottle that is located near the
hypochlorite tank.

i) Emergency Eyewash and Safety Showers.

Emergency eyewash stations and safety showers shall be provided at all hypochlorite installations where concentrated hypochlorite
solutions, containing 5% or greater available chlorine by volume, are handled in containers greater than 55 gallons. Where
hypochlorite solutions are used at remote locations or in quantities of 55 gallons or less on site, safety showers are not required
and alternative emergency eyewash may be provided
Keynote 12 on Drawing M1.0 calls out a portable eyewash station
